There is a difference between what triggers an unlock and what people assume triggers it. How to Unlock Excel File is a good example of that gap.

Small details matter more than they should here, so read the order of steps carefully. If something here stops matching what you see on screen, the game has probably changed a value in an update. Anything marked optional really is optional, so skip it without guilt.

The short answer

The unlock fires on a specific condition rather than on progress in general, so aim directly at that condition instead of playing more.

The quickest way to meet it

If you are short on time, the first section alone is usually enough. Treat the numbers as a guideline; your exact result depends on your setup and current version. Unlocks that depend on a hidden counter are the ones that generate the most bad advice. Most advice on this topic assumes you already know half the answer, which is exactly the problem.

Start with the simplest option before touching anything that is hard to reverse. Nothing below requires mods, paid tools or an account on some sketchy site. One clean run beats five rushed ones, both for results and for your patience.

What the requirement actually is

There is a fast way and a safe way, and they are not the same thing. If something here stops matching what you see on screen, the game has probably changed a value in an update. Most advice on this topic assumes you already know half the answer, which is exactly the problem.

  • Check the version you are running before following any step-by-step advice.
  • Write down what you changed, so you can undo it if the result gets worse.
  • Keep a spare loadout for the attempts that go badly.
  • Back up your save if the game gives you the option.

Mistakes worth avoiding

  • Changing several settings at once, then having no idea which one helped.
  • Following a guide written for an older version and assuming nothing moved.
  • Skipping the preparation step because it looks boring, then repeating the hard part four times.
  • Giving up one attempt before the point where it usually clicks.
